Non-occupant borrowers
A family member or other eligible co-borrower may be able to help qualify even if they will not live in the home.
Fannie
Fannie permits non-occupant borrowers on eligible principal-residence transactions subject to the applicable LTV, underwriting and borrower-relationship requirements. At least one borrower must satisfy the occupancy requirement.
Income and debt count
The non-occupant borrower's income, credit and liabilities become part of the mortgage underwriting profile; adding a borrower can help income while also adding debts or credit risk.
Agency Difference: Freddie permits eligible non-occupying borrowers under its own requirements. Product-specific rules—especially affordable products—can differ, so compare before assuming the same structure works under both agencies.
Could the other agency solve this? Fannie Mae and Freddie Mac are not identical. If this scenario fails under one agency, compare the other agency's current rule and AUS result before assuming conventional financing is unavailable. A lender overlay is also different from an agency prohibition.

Occupancy must reflect the borrower's actual intended use. Misrepresenting occupancy can constitute mortgage fraud.
